Good Evening,
I was pruning begonias when an Oregon Nuthatch landed on the lip of
the water basin next to me. Three common species are the Oregon Junco,
the Oregon Chickadee, and the Oregon Nuthatch. Each of them has a patch
of rusty brown on them. Otherwise they are like their cousins out
east. It is starting to smell like fall, the birds are dropping lower
in the trees. Squirrels are racing along the highest limbs freeing them
of their cones. As they fall they bounce off of every limb beneath.
Great dispersal mechanism, but you need a hardhat to walk around.
The sun snuck a CME into the flow of earthward ions. It is due
tomorrow so there may be a blackout, or there may be more noise, or
there could be more QSB. We shall see, it could miss us entirely. Kind
of like those cones falling from the sky. I will switch between my 20 m
dipole and the 40 meter vertical. The reason I have not used a dipole
for the net is because they are too directive. An inverted V grabs a
wider swath and sends a weaker signal. One of those engineering trade
offs where there are no real winners, only compromise.
Please join us on (or near):
14050 kHz at 2200z Sunday (3 PM PDT Sunday)
7047 kHz at 0000z Monday (5 PM PDT Sunday)

I banged on some code until it mostly works. This is a video of the
direct contribution to the electric field of a resonant one-half
wavelength horizontal dipole. It starts with a series of still shots
taken as I edited, compiled, and ran the application for a sequence of
heights above ground. Then I demonstrated the application at yet
another height. Finally I recompiled with a vertical (monopole) antenna
pattern. I am currently working on code for the reflected portion of
the E field. If I map the direct and reflected parts separately, then
add them together with a ground reflectivity coefficient, I can model
the E field over various soil types.
